Can you recompile Gambas with debugging information enabled? Or at least 
the QT4 component.

To do that:

$ cd </path/to/gambas/sources>/gb.qt4
$ make clean
$ make "CFLAGS=-O0 -g -fvar-tracking" "CXXFLAGS=-O0 -g -fvar-tracking" -j2
...
$ sudo make install
...

Then you can get the backtrace again, and we should have the function 
names and know exactly where it crashes.
